'llVIlEtE-SPBCtNG-FZAKKHG Application filed .l'nl l3,

To all whom it may concern.

Be it known that l, BERT la. VAN URBIZAN, a citizen of the United States, residi at Detroit, county of l/Vayno, State or. oigan, have invented certain new and useful Improvements in Wire-Spring-Making ll'lachines, of which the followin is a specii'icacation.

This invention relates to improvements in wire spring making machines. My present improvements relate particularly to the type of wire spring making machines shown in my application for Letters Patent, filed June 2nd, 1921, Serial No. 474,399.

lhe main objects of this invention are: First, to provide in a wire spring making machine, an improved governing means whereby uniform springs are produced from the wire which. varies in gauge and hardness, as is the case with ordinary commercial wires adapted for spring making;

Second, to provide an improved wire spring making machine by means of which springs are produced with uniform size in the matter of coiled diameter and also in length;

Third, to provide an improved wire spring making machine in which the diameter of the coils and the height of the spring is automatically governed under varying conditions of stock;

Fourth, to provide an improved wire spring making machine which is very economical in the amount oi wire consumed and that the forming means are automatically governed and adjusted to meet varying conditions of stock;

Fifth, to provide an improved wire spring making machine having the above and other advantages, and which will appear from the following description, which is invariably compact and durable in structure and not likely to become inoperative through breakage or wear.

Further objects and suggestions relating to details of the construction will appear from the following specifications.

The structure embodying the features of my invention is illustrated in the accompanying drawings, forming part of the specifications in which Fig. 1, Sheet 1, is a plan view of wire spring making machine embodying the features ct my invention; parts ot the 1.92%. Serial No. ave-see.

In tie accompanying drawings, similar reference numerals refer to similar parts throughout several views and the section views are taken looking in the direction of arrows at the ends of the section lines.

In the accompanying drawings, I have not attempted to illustrate the structural features of the frame as it will be understood that it is designed namely with a view of supporting the several parts in proper relation. The wire bale supporting mechanism is not illustrated, but is preferably that shown in my copending application herein referred to.

A wire 1 is fed to the coiler mechanism by means of the feed rolls 2 arranged in co-acting pairs (see Fig. 2). The wire is fed by these feed rolls through a supporting and guide tube 3, it being projected against the coiler block 4, the second guide 5 supporting the wire as it is promoted against the coiler block (see Fig. 7). The mounting of this coiler block is shown in detail in Figs. 20 to 22, sheet 11, the coiler blocking being mounted on the vertical rock shaft 6, having a segment 7 secured thereto by the pin 8 and adjustably connected to the arm 9 by the worm 10 mounted on the arm to coact with the segment. The main purpose of this adjustable connection is to compensate for wear in the coiler block L IS a detail view or a of the diameter govltll) without changing the range of movement lIlU lid
